Add support for "source info" and use it to fix MI's -symbol-list-lines.
This patch adds support the command 'source info' as follows: (lldb) help source info Display source line information (as specified) based on the current executable's debug info. Syntax: source info <cmd-options> Command Options Usage: source info [-c <count>] [-s <shlib-name>] [-f <filename>] [-l <linenum>] [-e <linenum>] source info [-c <count>] [-s <shlib-name>] [-n <symbol>] source info [-c <count>] [-a <address-expression>] -a <address-expression> ( --address <address-expression> ) Lookup the address and display the source information for the corresponding file and line. -c <count> ( --count <count> ) The number of line entries to display. -e <linenum> ( --end-line <linenum> ) The line number at which to stop displaying lines. -f <filename> ( --file <filename> ) The file from which to display source. -l <linenum> ( --line <linenum> ) The line number at which to start the displaying lines. -n <symbol> ( --name <symbol> ) The name of a function whose source to display. -s <shlib-name> ( --shlib <shlib-name> ) Look up the source in the given module or shared library (can be specified more than once). For example: (lldb) source info --file x.h Lines for file x.h in compilation unit x.cpp in `x [0x0000000100000d00-0x0000000100000d10): /Users/dawn/tmp/./x.h:10 [0x0000000100000d10-0x0000000100000d1b): /Users/dawn/tmp/./x.h:10 The new options are used to fix the MI command: -symbol-list-lines <file> which didn't work for header files because it called: target modules dump line-table <file> which only dumps line tables for a compilation unit. The patch also fixes a bug in the error reporting when no files were supplied to the command. Previously you'd get: (lldb) target modules dump line-table error: Syntax: error: no source filenames matched any command arguments Now you get: error: file option must be specified.
